标题 :Synthesis of poly-alpha olefin and use thereof
发明人：SONG WEI; HEILMAN WILLIAM J
权利人:SHELL OIL CO
摘要:One or more oligomers of an olefin are prepared in the presence of a single-site catalyst. Preferably, the olefin is an α-olefin, and the oligomers are a poly-alpha-olefin (PAO). The PAO so prepared is completely or substantially free of tertiary hydrogen resulting from isomerization. Consequently, the PAO possesses improved biodegradability, improved oxidation resistance, and/or a relatively higher viscosity index. The PAO has many useful applications, such as a component of a lubricant.

发明人：MCALPINE SHELLI R; TAYLOR RACHEL E; BOLLA MEGAN L; SEGALL ANCA M
摘要:The invention provides a method for making a combinatorial library of cyclic compounds, such as Holliday junction-trapping compounds, comprising the steps of (a) obtaining a plurality of trimers according to the generic structure X 1- X 2- X 3 , wherein X 1 , X 2 and X 3 can be independently any naturally or nonnaturally occurring amino acids or peptidomimetics thereof; (b) optionally coupling a spacer S to the trimer at either end; (c) cyclizing two trimers or trimer-spacer conjugates in a head-to-tail orientation; thereby obtaining a combinatorial library of compounds, wherein the library does not include an unmodifed or naturally occurring Holliday Junction-trapping compounds. The invention additionally provides methods macrocyclic compounds that are synergimycin derivatives.

摘要:The invention relates to a strain of Trichoderma harzianum Td50b, deposited with the deposit number NCAIM (P) F 001412, which produces the exohydrolases involved in the degradation of plant material and presents antagonism against pathogens of ornamental crops, including through synthesis of odorant volatile compounds with antifungal activity. The strain was used to produce a controlled release compositions that promote the colonization of the material intended to be composted, assuring the survival of propagules not-liberated after the initial colonization of the substrate with the strain producing fungistatic volatiles compounds, including for the dormant propagules of the same strain, and, on the end, accelerate the obtainment process of composts intended to be used for mulching of the ornamental crop soil, in order to protect them against the attack of pathogen agents.

摘要:The present invention relates to a mutant strain of a methylotrophic organism, a process for the production of a protein in a methylotrophic organism and a method for the selection of methanol oxidase deficient mutants of methylotrophic organisms. The present invention provides a mutant strain of a methylotrophic organism wherein the original chromosome of said mutant is defective in effecting synthesis of active molecules of at least one protein encoded by a methanol inducible gene. Upon introduction of at least one, preferably more than one expression casette, wherein each of said expression casettes comprises an regulon of a methanol inducible gene or a functionally equivalent sequence, a DNA sequence coding for a protein to be expressed, and optionally a terminator, and wherein expression of said DNA sequence is under control of said regulon a strain is obtained, which shows a remarkable over-expression of the protein encoded by the gene of the expression casette. These strains are well suited for production of pure proteins, such as methanol oxidases free of catalase.
